Construction shall be performed in such a manner that the pavement surface above the pipe line does not have more than 1/2 inch of settlement when measured with a 10-foot straightedge.

Provide suitable bracing between jacks and the jacking head so that pressure shall be applied to the pipe uniformly around the ring of the pipe. The jacking head shall be of such weight, construction, and dimensions that it shall not bend or deflect when full pressure is applied at the jack. The jacking head shall be provided with an opening for the removal of excavated material as the jacking operation proceeds. The Contractor shall set the pipe to be jacked on guides that are straight and securely braced together in such manner as to firmly support the section of pipe and to direct it in the proper line and grade as jacking operations proceed.
